The skin flora is naturally populated with microorganisms. Each region of the body has its own permanent colony (resident skin flora). When microorganisms settle only temporarily on the skin flora, they are referred to as transient. Such settlements can occur when a person touches another person or an object. Then any bacteria, fungi and viruses that are present on the surface are transferred onto one’s own skin. Using hand sanitation is primarily intended to eliminate the skin’s transient flora, so-called airborne germs.
